"Not true. "
Go find a decent historian Keith
Stalin removed all the socialists from the Soviet leadership and had the main one, Leon Trotsky, murdered
Stalinism has sweet fulck all to do with Socialism - it was a system gone wrong, whith Stalin the main cause of its downfall
On the other hand, Hitler was supported into power by German Capitalism - it was a natural progression of the defeat of the left in Germany
The main supporters of Nazism were the giant companies - Krupps and Essen among the greatest, along with numerous American financiers   
E. Roland Harriman Vice president of W. A. Harriman & Co., New York
H.J. Kouwenhoven Nazi banker, managing partner of August Thyssen Bank and Bank voor Handel Scheepvaart N.V. (the transfer bank for Thyssen's funds)
J. G. Groeningen Vereinigte Stahlwerke (the steel cartel which also funded Hitler)
C. Lievense President, Union Banking Corp., New York City
E. S. James Partner Brown Brothers, later Brown Brothers, Harriman & Co.
Politicians in Britain, included Churchill, while not becoming directly involved, appeased the rise of German fascism, looking on "New Germany to act as a bulwark against Bolshevism"
America's greatest ally in Vietnam was self proclaimed Hitler admirer, Marshall Kee, the murderous Greek Junta, supported by Britain and the Chilean fascists, led by Mrs Thatcher's friend, mass murderer, Augusto Pinochet were all extreme right wing dictatorships
We know exactly how "cenrte" your right-wingism is.
Dream on Keith - fascism is the province of the right - and remained so throughout the 20th century.
